Claims (1)
レーム上を回動するための左右一対の滑動機構に
夫々フリーベアリンクの滑動する直線案内溝を、
該溝の仮想垂直線交点がウエブ入側ロールの円周
外縁中央近傍になるように八の字状に構成して設
け、該近傍がロール支持フレームの回動仮想支点
になるようにした機械的回動支点のないセンター
ピボツト方式のガイドロール機構。 A pair of left and right sliding mechanisms for the roll support frame that supports the roll to rotate on the base frame is provided with a linear guide groove in which the freebear link slides, respectively.
The groove is configured in a figure eight shape so that the intersection of the virtual vertical lines is near the center of the outer circumferential edge of the roll on the web entry side, and the vicinity becomes the virtual fulcrum of rotation of the roll support frame. A center pivot guide roll mechanism with no pivot point.
